The process skid has a Class I Group D Division 1 Electrical Area Classification due to the presence of instrument and power gas, which vents continuously. This must be considered when locating other electrical or flame fired equipment in the area of the skid to ensure safe operations. No smoking or any other open flames should be permitted in the immediate vicinity of the unit.
THIS IS A HIGH PRESSURE NATURAL GAS CONDITIONING UNIT; THEREFORE ALL APPROPRIATE INDUSTRY AND COMPANY SAFETY PRECAUTIONS AND STANDARDS MUST BE ENFORCED.
The fundamentals of a good layout and design cannot be over emphasized. They provide an irreplaceable safety factor throughout the life of the project, often at very little increase in initial cost. DPC equipment is specially designed to remove the heavier hydrocarbon components from natural gas. Unlike methane, these gaseous components are all heavier then air and must be treated differently then methane. The DPC refrigeration chiller packages are non-electrically classified and must be spaced safely from combustion sources. Industrial risk guidelines in practice all over the world use the OIA/RIA gasoline plant spacing charts. Although a a closely spaced facility may meet the letter of the law of the NEC or API codes, it is not considered Best Engineering Practice, The buyer must beware; many engineers and even some of our competitors confuse the application of the various standards, recommendations and codes. Usually a judicious equipment layout will show that the open electrical, usually located in a corner of a typical lease or facility plot will also be convenient to locate other sources of combustion, such as glycol reboiler burners or incoming power infrastructure.
